SPECIFICATION forming part of Letters :Patent` No. 562,450, dated June `23, 1896. Applimionled my 5,1895. Seriana. 555,081. (No model.)

To a/ZZwI/om zit/ may concern..-

A Be it known that LI-IENRY A; BAXTER, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented a new and useful Car- Shunter, of which the following is a specifi-` cation.

My invention relates to improvements in car-shunters, in which a lever, fulcrumed to and supported by aleg resting upon the rail, operates on said fulcrum in movin g cars, said lever being provided with a second leg which coacts with the rst in following the car, and also with a push-bar which operates against the edge of Athe car; and the objects of my invention are, i first, to provide; for the ad j ustment ofthe fulcrum whereby more or less purchase and a greater or less speed may be obtained; second, to render the push bar or arm adjustable to any height of car; third, to provide a bearing-block for the end of the push-bar; fourth, to provide a bearing-wheel which will allow the shunter to follow the moving car without the operation ofthe lever, and, fifth, to provide means whereby the bearing-wheel operates inm conjunction with the fulcrum-leg in moving a car, and also acts as a carrier-wheel in transferring the shunter from place to place. by the mechanism illustrated in the accompanying drawings, in which- Figure l is a perspective view of my car- 'shunterg Figs. 2 and 3, a front and side View, respectively, of the bearing-wheel; Fig. 4, a perspective view of the bearing-wheel; Fig. 5, a side view of the adj listing-bolt on large scale; Fig. G, a perspective view of the spring used in the adjusting-bolt; Fig. 7, a broken portion of the operating-lever,showing one of the catch-slots for holding the bolt; Fig. 8, a plan view of the bifurcated end of the operating-lever; Fig. 9, a side elevation of a portion of the follower-leg, showing the carrier-block and its connection with the fulcrum-leg; and Fig. 10,a plan view of the pawlrod.

Similar letters refer to similar parts throughout the several views.V i 4 The fulcrum-leg E, lever A, push-bar O, follower-leg D, and carrier-wheel F, which is j ournaled in the follower-legi), constitute the I attain these objects.

parts dependent upon each other in pushing or shunting a car. The operating-lever A is provided with a removable part B, and slot a.,

which receives the fulcrum-leg E,`the pushv arm C, and the follower-leg D, which is connected thereto bythe links i and is provided at the lower end with a wheel F, pawls f, rod e', and block e. The bifurcations of the lever A,which are formed by the slot ci, are provided with apertures a', a2, a3, and a5, which ter minate on one side of the lever in the slots n2 andin connection therewith provide for the operations of the bolts d,

`The fulcruln-legE is attached tolever A in the slot @bythe bolt cl and is adjustable therein by means of the apertures a, a2, and as and is adapted to engage the pin d? of block e by means of the aperture d3, fitting said pin when the block is raised, as indicated by `dotted lines in Fig. `l. This engagement of the pin cl2 with the leg E supports the leg and raises the pawls from contact with the ratchet-hubs f of wheel F, as indicated in` Fig. 9, thus allowing the shunter to be Wheeled about at will.

rail and guide the leg and have their forward edge sharpened, so as to nip the rail when the leg E is under pressure.

The push-arm C is mounted in the slot a, between the outer ends of the bifurcations of the lever A, and is adjustable therein by means of a removable bolt CZ, operating in apertures d' of said arm, and is provided with a pressure-block 7i, pivotally attached to the upper end, and a box-strap C', at the lower end, which fits about the leg D.

The leg D is provided with a box-strap C2 at the upper end which ts about the leg C. These straps C and C2 hold the arm O and leg D together, and the bolt CZ, operating in apertures d in arm C, an d the links i, pivotally j attached to the lever A and leg D, sustain the said arm and leg in their relative positions.

The lower end of the legD is bifurcated and provided `with a `bearing-wheel F, journaled in said bifurcations, and pawls f, pivotally attached thereto and adapted to engage with ratchet-teeth provided in the hubs f of said bearing-wheel. These pawls f are conneeted with `the block e by a rod @"which 1 passes through the block and provides for raising the pawls out of engagement with the ratchet-teeth of the wheel F when the block e is raised, as indicated in Fig. 9. This rod e also acts as a spring to force the pawls f well down into the ratchet-teeth of the hubs f', when the block c is down and the shunter is in operation.

The hubs f of the follower-wheelF are set upon the wheel so that the points of the ratchet-teeth in one hub are centrally located with reference to the lspace between the points of the teeth in the opposite hub. This is clearly indicated through the broken por' tion in Fig. 2, and is to provide for the engagement of one of the pawls at' all times when the shunter is operating.

As heretofore explained the pawls f are pivotally attached to the bifurcations of the leg D and may be raised by the rod e', which passes through the block e and is attached to the pawls f by the ends thereof passing through the pawls; When the block e is down vupon the leg D, the rod e',wl1ich fits tightly in the block e and has bearing against its sides, Operates as a springin holding each pawl in con tact with the hubs of the wheel F. This spring in addition to the weight of the pawl insures the contact of the pawl with the ratchet-teeth at all times. 7When desirableto raise the pawls, the block e is raised and the pawls strike the flanges of the wheel F. This holds them from raising farther up, and the block c can be forced upward until rest` `ing in the position indicated in Fig. 9.

The face of the bearing-wheel F is de'- pressed to fit the top of an ordinary rail and is provided with Veshaped projections following the contour of the face, forming angular' ridges beginning at the edge of the face and terminating at the center. This is clearly shown in Fig. 2. This wheel is journaled in the bifurcations of the leg D and is set so that the apeX of the angle formed by the V- shaped ridges point rearwardly when in contact with the rail. Thus, when back pressure is upon the leg D, one of the pawls f engage one of theratehet-hubs and the angularprojections on the wheel nip the rail.

The pressure-block h operates upon the pivot 71.. The bottom plate h2 is provided to en gage the end of the arm C to keep the block from tipping too far.` This blockis very useful, as, where the upper end of arm C is simply bifurcated, the machine is often strained and the bifurcations broken by reason of the different angles at which the arm operates with reference to the corner of the ear, the langles thus taken causing the total pressure to come upon a single bifurcation, while with my pressureblock the arm C may take the necessary angle and the block yet remain in full contact with the corner of the car.

I make my machine adjustable for any leight of car by means of the holes d and bolt c This bolt CZ I construct so as to lock and unlock automatically in the several holes d. This I accomplish by means of a flat spring n, bent V-shaped and secured in the slot n. This spring is convex on its surface o, near the base p. As the bolt CZ enters the hole d', the spring is compressed; but when the bolt is in and turned so as to bring the slot n in line with slot n2 of the fork A the spring opens and retains the bolt, as shown in Fig. 5.

Vhen desirable to withdraw the bolt, it is turned to the right or left and the projecting surface of fork A about the hole a5 forces the spring into the slot n and the bolt may be withdrawn. This same form of bolt is elnployed and the same operation performed in adjusting the leg E.

In operating my machine I first place it against the car to be moved, in the position shown in Fig. l. I then raise the handle B.

This moves the leg E', sliding the toes e3 along the rail, but does not move the car. When downward pressure is placed upon the eXtension B, the lever A operates on the fulcrumbolt d and causes an upward and forward movement of the pressure-arm C, and also advances the leg D by means of the links t', operating on the pivots 7a and m, the wheel F revolving forward and the upper end of leg E also advancing with a circular movement from the toes e3 as a center. After the lever has been pressed down it is raised with aforward pressure to keep the pressure-block n against the car and to roll the wheel F along the rail. XVhen raising the lever, the fulerum changes from the leg E to the pivots m of links i; and, as clearly seen, this movement shortens the distance between the bearing-wheel and the pressure-blo`ek and allows the wheel to advance, as explained. This raising of the lever also advances the toes c3 of leg E along the rail ready to nip the rail anew when downward pressure is brought to bear upon the operating-lever.'

If the ear moves rapidly after being started, the shunter follows the car by reason of forward pressure on the extension B, but if desirable to increase the speed the lever A is operated accordingly.

Any back movement of the ear is obviated by the pawls f, engaging the ratchet-hubs f',

ICO

and the angular projections of the wheel F,

nipping the rail.

vThe fulcrum of leg E is adjustable in slot a of lever A. This allows a rapid movement of the car, when lightly loaded or empty, by placing the fulcrum-bolt in the rearward aperture a of lever A, and when heavily loaded a slow but more powerful movement of the lever can be attained by placing the bolt in the forward aperture a3, though ordinarily the bolt is placed, as indicated, in the aperture a2.

Then desirable to move the shunter about, I raise block e, drop leg E until the aperture d3 engages pin d2, the pawls f being thus disn engaged,and the shunter may then be wheeled about at will.

I am aware that'prior to my invention car 562,45() j t y broken and the shunter renderedfuseless thereby. The shunter has also in many instances fallen to the ground owing toa rapid movement of the car, the arrangement of the pivots and fulcrum and general construction of the shunter rendering it impracticable to operate the lever fast enough to keep the shunter in position.
